IMPROVEMENT IN GOGKS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES M. ALBURGER, of Philadelphia, Philadelphiacounty, Pennsylvania, have invented a new and useful ImprovementinCompression Cocks; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable-others skilledin the art to inakc and use the same, reference being had to .theaccompanying drawings, forming a part of this specification, in which-Figure 1 is a central longitudinal section of my improved cock.

Figure 2, a cross-section of the screw-spigot, taken on the line a z,iig. 1.

Figure 3, a detached section view of the spigot.

Figure 4, a bottom end view of the same.

l Similar letters of reference indicate corresponding parts.

This invention relates to an improvement in compression cocks andfaucets, and it consists in thc combination of the follower providedwith an elastic and metallic packing upon. its lower end, with a flangedthimble, f spiral spring, and elastic packing near its upper end, saidthimble fitting over the upper sidcor top of the spring, therebypreventing the sharp edge of the latter from cutting away and destroyingthe packing, as will be hereinafter more fully described.

A represents the follower upon the spigot C of an ordinary compressioncock, B, 'rrp which a is theiifiuitb way through' the raisedvalve-seat'c. The follower A is provided with a washer, e. made of blocktin or any suitable soft metal or other substance, which washer has acircular groove in the face for-med to t over the upper side of theraised seat c, upon which the spigot bears when the cock is closed.Between the end of the' follower A and the metallic Washer e is placedan'elastic packing or washer, e', whereby ap'erfect joint is formedbetween the softmetallic packing and `the follower. Upon the upper endof the follower A, and surrounding the spigot C, a spiral spring', D, isplaced, said spring having its coils iiattened, as shown in fig. 3, itsupper end d', bevelled upon the under` side to t into a correspondingbevel in the centre onmiddlecoil. The spigot C is provided with abevelled ring, E', firmly secured thereto, as seen in figs. I and 3,tlieupper inclined side of the ring fitting and working in thecorrespondingly inclined cap G, attached to the top of the cock, throughwhich the spigot works. Surrounding the spigot above the spring D, andresting against the under side ofthe ring E', is placed the packing E.In the compression cocks heretofore made this packing has, by the actionof the sharpened or bevelled edge of the upper end of the spiral spring,been cut away and worn out, rendering the frequent application of a newpacking necessary. To obviate this diieulty I place inside of the innercireumvference of the spring D a thimble, F, whose upper edge is turnedover, forming a flange resting upon the upper" side of the spring,thereby preventing its sharpened end d from coming in contact with thepacking, as is evident.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The follower A, having its metallic packing e and elastic packing e', incombination with spring D, flanged thimble F, packing E, and spigot C,substantially as described for the purpose specified.

The above specification signed by me this 21st day of January, 1867.
